解决报错：Could not import the lzma module.

PYTHON执行报错
/usr/local/python3/lib/python3.7/site-packages/pandas/compat/__init__.py:124: UserWarning: Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.
  warnings.warn(msg)

 解决办法：

一， 在LINUX安装支持包

yum install xz-devel
yum install python-backports-lzma
pip install backports.lzma

二，进入lzma配置文件 cd /usr/local/python3/lib/python3.7/  ,运行 vi lzma.py
        修改一下（ 加入try : except ）

try:
    from _lzma import *
    from _lzma import _encode_filter_properties, _decode_filter_properties
except ImportError:
    from backports.lzma import *
    from backports.lzma import _encode_filter_properties, _decode_filter_properties

完成！
